The BT-620 is a compact, battery-operated particle counter with six selectable size channels, an integrated printer, and housed in a portable stainless-steel case. The device’s flow rate is 1.0 CFM (28.3 LPM) and is maintained with volumetric flow control for improved accuracy. This benchtop particle counter has a large, easy-to-read display, audible alarms, and an internal printer that work together to verify particulate levels. If the particle count exceeds the user’s pre-set limit, the audible alarm will sound, and the screen display, sample history, and printout will indicate an alarm event. Two programmable count alarm limits may be set.
 

Ideal for use in cleanrooms, the BT-620 was designed to easily integrate with existing building automation systems, facility software, processors, or may be used as a standalone unit.
